CENTRING THE SANDING BELT
Belt centring is achieved by turning the knob (B) in either direction.

which side it has a tendency to move (Fig. 11);
2) Start belt rotation in pulse mode by pressing the START and STOP buttons alternately while
at the same time turning the knob (B) (Fig. 12): turn the knob clockwise to move the belt
towards the inside of the machine and turn it anti-clockwise to move it outwards.
3) Start the machine to check that the belt is correctly aligned.
If necessary repeat the belt centring procedure.
